Deprecated. com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

A listener of data transfer events.

A transfer usually progresses through multiple steps:

  1. Initializing the underlying resource (e.g. opening a HTTP connection). onTransferInitializing(DataSource, DataSpec, boolean) is called before the initialization starts.
  2. Starting the transfer after successfully initializing the resource. onTransferStart(DataSource, DataSpec, boolean) is called. Note that this only happens if the initialization was successful.
  3. Transferring data. onBytesTransferred(DataSource, DataSpec, boolean, int) is called frequently during the transfer to indicate progress.
  4. Closing the transfer and the underlying resource. onTransferEnd(DataSource, DataSpec, boolean) is called. Note that each onTransferStart(DataSource, DataSpec, boolean) will have exactly one corresponding call to onTransferEnd(DataSource, DataSpec, boolean).
